ABTICULATED-LOCOMOTIVE-FRAME CONSTRUCTION.

Application filed June 25, 1925. Serial No. 39,437.

This invention relates to locomotives of the character shown in my issued Patent No. 1,536,036 of April 28th, 1925.

The locomotive of such patent has a main frame, the rear end of which terminates in the vicinity of the forward end of the the.

box. Extending rearwardly from, and articulated to, the main frame is a supplemental frame.

This invention hast?) do particularly with the form of connection between these two frames, the purpose of the invention being to provide a safe connection.

I accomplish the foregoing by means of a construction which I have illustrated in preferred form in the accompanying drawings, wherein Fig. 1 is a diagrammatic section of the side elevation of'a locomotive of the character described and equipped with my improvements Fig. 2 is a fragmentary view, partially in section, illustrating my improvements on an enlarged scale; and

Fi 3 is a plan'view of the-device shown in F1 2 drawn on a still larger scale.

Re erringnow to Fig. 1, the locomotive boiler 8 is in part supported upon the main frame 9, which terminates at the forward end of the fire box 10 and in part upon the supplemental frame 11, articulated to and p extending rearwardly of the main frame.

The form of support of the superstructure on the frames is not shown, as it forms no specific part of this invention. The articulated frame 11 may have one or more axles or driving wheels.

Referrin now more particularly to the connection etween the frames, this is indi-.

cated as a whole by the reference character A in Fig. 1. The connection is clearly shown in Figs. 2 and 3. Extending between and bolted to'the rear ends of the members of the main frame 9 is a casting B, which casting has a base plate 12 and a shelf or plate 13 thereabove, providing a pocket 14. Reenforcing ribs 15 connect the pocket portion with the side attaching flanges 16 and the front attaching flange 17, it being understood that all of the parts are cast'integral. The base plate 12 and the shelf 13 are apertured to receive the pin 18, such pin being 1151512111 place by the keeper 19. ,Extendin between and connecting the fiarlward en sof the side members of the frame 11 is another casting C, which casting comprises side attaching flanges 20 extending between which are three plates 21,

- 22 and 23, uniting at the rear with the wall 24. The plates 21 and 22 unite at their forward ends to form a tongue 25, which tongue is apertured so as to. receive the pin 18 above referred to. Extending transversely of the plate 21 isan upstanding reenforcing rib 26, which connects also with the side flanges 20, the plate 23 being provided with a similar but dependent re-enforcing rib 26. Connecting the plates 22 and 23 are spaced webs 27 and 28, such plates, the webs and the rear wall 24 forming a pocket 29. The plates 23 and 24 have central bosses 30 which are apertured to receive the pin 31, such pin being adapted to be held in place by the keeper 32.

The plate 12'has a boss 32 and a safety bar 33 has its forward eye 34 fitted over the boss 32. The safety bar 33 has a rear eye 35 for the reception of the pin 31. The two eyes of the safety bar have a loose fit over the boss 32 and the pin 31 respectively so that under normal conditions no pulling or bufiing stresses are transmitted thru the safety bar but only thru the tongue 25. In case of breakage, however, of the tongue or of the main pin 18, the safety bar functions. The importance ofthis will be readily apreciated when it isseen that the rear end of the locomotive boiler is carried upon the supplemental frame.

What I claim is:

1. In combination in a locomotive, a main frame, a trailer truck, means for hinging the I truck to the main frame, and a supplemental safety bar connecting the main frame with the articulated truck.

2. In combination in a locomotive, a main frame, an articulated frame, a hinged connection thereof including a tongue, and a supplemental safety bar connecting the main frame and the articulated frame.

3. In combination in a locomotive, a main frame having the usual side members, a casting connected to the rear ends of the side members and having a draw pocket, a truck frame to the rear of the main frame having side members, a casting connecting the forward ends of said side members, said castin having a tongue adapted to roject into said draw pocket, a pin carried y the first casting in said draw pocket, a pin carried by the second casting, and a safety bar for said pins, the tongue having an eye for the reception of the pin carried by said first cast- 1n i. In combination in a locomotive, a main frame having the usual side members, a casting connecting the rear ends of said side member, said casting having a draw pocket and a draw pin, and also having a boss adapted to surround a portion of said pin, an articulated frame having side members,

1 a casting connecting the forward ends of said side members and having a tongue with an eye adapted to fit said pin within said draw pocket, said second casting also having a pocket and a pin, and a safety bar'connecting the two castings and having an eye fitting over said boss and an eye to receive said last pin.

In testimony whereof, I have hereunto signed my name.
